Grease trap cleaning in High Barnet, done properly
Grease traps sit between the sinks and the drain, holding back fats, oils and grease. As the waste water cools, the grease floats and stays in the trap while the water carries on to the drain. Eventually it fills and has to be emptied and cleaned. Typical jobs include washing-up water that won’t drain away and foul odours from the grease trap, across school and care home kitchens, under-sink grease traps and restaurants and takeaways.
London’s sewers are known for fatbergs, built up from fat, oil and grease washed down drains. Regular grease trap cleaning keeps a kitchen in High Barnet from adding to the problem.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

Questions from High Barnet
Do you clean school kitchens in High Barnet in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. With about 21 schools and colleges on the FSA’s register within roughly a mile and a half of High Barnet, it pays to plan holiday dates ahead. Just call 0345 646 2711, or email photos with your term dates and we’ll plan around them.
Who would carry out a food hygiene inspection at a kitchen in High Barnet?
The local authority for High Barnet is Barnet council, and its environmental health team does the inspecting. How often a business is inspected depends on the council’s risk rating for it, so the kitchen needs to be ready at any time.
What types of grease trap do you clean?
We cover under-sink, inline and interceptor units. Each one is emptied, cleaned and checked in the same careful way.
What problems does a full grease trap cause?
A full trap can’t catch any more grease. The grease hardens in the pipes, leading to blocked drains and smells and can end up adding to sewer blockages.
Do you provide a certificate or report?
Yes, on every job. It’s a dated, written report with photos, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. Keep it in your maintenance log.
Which records should we keep?
Visit reports, certificates and your in-house cleaning logs. They’re what an insurer, fire officer or EHO may ask for, so keep them together and easy to find.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not legislation, but it’s the standard people check against.
What about areas you can’t get to?
We record them on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
Different parts, different methods
Baffles and outlets
Clean water leaves through the outlet. If it’s blocked or greasy, the trap backs up.
School, care home and staff kitchens
Care home and hospital kitchens need their drains working all the time. We fit visits around mealtimes.
Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Do not wait for a blockage to book a clean
- Make sure the trap can be reached easily
- Keep strainers in every sink
- Tell us if your menu or hours change
Collect waste cooking oil separately rather than pouring it down the sink, and the trap will stay cleaner for longer. It’s the single easiest way to help.
If the sinks are slow or smelly, the trap may be full. Getting it cleaned now can stop a full blockage down the line.
Grease trap cleaning in High Barnet: local notes
Food Standards Agency data counts about 52 cafés, restaurants and staff canteens and about 24 sandwich bars and takeaways within about 1.5 miles of central High Barnet. Fat from washing up sets hard in pipes, and kitchens like these produce plenty of it. Environmental health officers from Barnet council inspect food businesses in High Barnet. The state of floors, drains and hard-to-reach corners all feeds into the inspection. Keeping a record of deep cleans and grease trap visits helps at inspection time. Most London kitchens cannot close in the day, so deep cleaning is normally done overnight.
If you cater for weddings or events at a historic house in the area (Wyllyotts Manor is about 2.9 miles north), deep cleans can be fitted between bookings. Hall kitchens near Christ Church or elsewhere in High Barnet may have older sinks and drains, so a grease trap check is worth adding to a deep clean.

Common problems we fix in High Barnet
Waste cooking oil poured down the sink overloads the trap fast. Even small amounts add up.
The symptoms we’re asked about most include:
- An under-sink unit that needs regular emptying
- A full, neglected grease trap
- A regular cleaning plan for the grease trap
- A kitchen drain that smells
A summer deep clean suits schools such as Foulds School, as the kitchen can be stripped back with no lunches to serve.

How we price grease trap cleaning
We do not publish a price list, because no two systems are the same. What we look at:
- Whether it’s a one-off visit or part of a schedule
- Any permits to work or inductions
- How big the system is
- How easy every part is to reach
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Any symptoms, from odd noises to smells or leaks
- Where the site is and what kind of site it is
- Detail shots of panels, filters and grilles
- Photos showing the whole system and its surroundings
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
What happens on the day
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes an hour or so for an under-sink trap, longer for a larger unit. Loading bays, visitor permits and roof access are the first things we ask about for a site in High Barnet.
- First, we find the trap and look at its connections.
- We make sure nothing drains into the trap.
- Grease and solids are removed from the trap.
- We clean every part of the inside.
- The trap is refitted, tested with water and the waste taken away.
How to prepare
- Clear the space around the work
- Have your last certificate or report to hand
- Allow time for equipment near the work to be turned off and cool down
Ask for a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

Leave it or put it right?
A blocked drain can stop a kitchen in its tracks. Sinks won’t empty and waste water can come back up. Keeping the trap clean reduces the risk. In High Barnet, a planned overnight visit is much easier than closing unexpectedly.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll go through it with you.
